Milk was not a common drink before the invention of the refrigerator. It spoils in hours if left out at room temperature and grows bacteria that makes it dangerous to consume. Russia, apparently addicted to dairy, came up with a unique solution to the problem. They put frogs in their milk.

This might sound disgusting, but the science checks out. Frogs have skin coated in a peptide that kills any harmful bacteria found in milk. Using the frog method, the milk still might have tasted a little funky, but it was safe to drink and dip cookies in. Next, find out what people did before cologne and perfume were invented.
